In a small bowl or cup, mix the sherry, soy sauce, and some water (as desired). Add the cornstarch and mix well. Set aside.
Heat a tablespoon of olive oil in a hot wok or pan and cook the chicken with salt and pepper. Remove chicken and set aside.
In the same pan, heat the other tablespoon of olive oil and cook the onion, then the garlic and ginger, and then add in all the vegetables, stirring often.
When vegetables are tender-crisp, reduce heat and add back chicken and add in sauce.
Cook until sauce thickens and coats all vegetables and chicken (just a few minutes).
After cooking, but before serving, drizzle with sesame seed oil if desired. Serve over rice.
Note: dish can be made more low-fat by removing some of the oils. You can also try adding nuts or other vegetables.
